Hi all,
I have enabled desktop effects of Kwin to have transparent panels. Currently I am using Keramik as window theme. My system is an openSUSE 11.2 with KDE 4.3.4 release 2 installed using openSUSE's KDE4 repositories.

My problem is that also window buttons (like close and minimize) are transparent; more precisely, the black part (i.e., the x of close and _ of minimize) is trasparent while other parts of the button is ok. If I choose a different window theme, like Plastik, such buttons are no more transparent. I think the problem is due to the color of the transparent part: in Keramik, the color is a pure black (#000000) while in Plastik is a very dark grey (#141312).

I will attach two screenshot: one with Keramik and another one with Plastik to highlight the effect...
